It’s impossible to answer a question of this nature, such as how difficult college physics is.

But let’s just assume that studying physics in college will, mostly, be difficult. Physics is difficult, which is something that both academics and students agree on.

Science has only been capable of proving it now. Finding an equation that captures how a system develops over time is one of the most prevalent aims in physics; yet, computer theory defines this task as difficult.

Although this is terrible news for physics students who believe a computer would eventually solve all of their homework issues, at least it means that they won’t face automation in their professional prospects.

There is yet a glimmer of optimism that physicists will figure out how to transform these ostensibly complex issues into forms that computers can solve.

There would be significant ripple effects across mathematics if such a simpler path were to be discovered since it would allow for the simplification of all the other challenging issues.

Is Physics Difficult?

In reality, physics is among the most difficult classes you can take, according to most individuals. It is easy-to-understand physics.

Physics is challenging for several reasons, including its extensive use of mathematics.

Physics encourages you to think abstractly and uses concrete mathematics to describe those abstract notions.

Concepts in physics are simple to understand. Arithmetic is easy to do. It is difficult to portray the former in terms of the latter while yet being able to explain it in the most accurate words.

We just don’t have a lot of practice doing it since there aren’t many factors that make us do it.

You only need to put in the effort after you have a basic understanding of what’s happening; before long, you’ll be an expert in physics.

You must have faith in your ability to master physics. Calculus required three tries for me to fully understand it after I spent my whole high school career failing arithmetic.

Anyone can learn physics if I could do it successfully and gain a bachelor’s degree in it.

To give oneself the best chance of understanding fundamental physics, here is a list of activities you must practice and abilities you need to acquire.

The Mathematics You Need for Elementary Physics

Even while physics typically requires a high level of numeracy, there are several particular mathematical concepts that you will encounter so frequently that it is crucial to ensure you are proficient in them.

The most popular math concepts in elementary physics are listed here.

1. Algebra

Since you are accustomed to seeing algebra, it would be more true to state that you will need to use algebraic thinking rather than real algebra.

Algebra is the area of mathematics that, in its widest sense, deals with symbols and the rules for their manipulation.

In your physics studies, you’ll frequently need to examine one symbol and come up with other symbols to represent it. Consider the force equation:

F(force) = M(mass) × A(acceleration)

You can rewrite this in two different ways:

F = M × (V÷t); V = velocity, t = time.

F = (D × vol) × (V÷t); D = density, vol = volume.

Solving many physics difficulties requires using this algebraic representation of one notion as another.

Your success depends on your ability to rewrite one sign as a combination of two or more other symbols (and vice versa).


Sine, cosine, and tangent calculations should be extremely easy for you.

This is essential for both mechanics and electromagnetics. This is mostly used to calculate the total of the force vectors and the angle at which they point.

Calculating an object’s speed or distance is not a straightforward task in physics.

You must determine its trajectory and angle of climb or fall. If you need to determine the route an item travels when forces from various directions meet, trigonometry might be helpful.

Calculus 1

mathematics offers you the means to determine an object’s acceleration at every given moment in time, in my experience you are constrained in what you can explain.

One of the most important concepts in learning physics is instantaneous acceleration, and you can’t do it if you don’t know how to compute the derivative of an equation that depicts the route an item follows.

The true benefit of learning calculus is that it improves your understanding of rates of change on an intuitive level.

Depending on how ambitious you want to be in physics, you’ll need to master a lot more than calculus (linear algebra, differential equations, and probability).

The greatest calculus you’ll need if you simply study Physics 1 or 2 is level 1, and more precisely, differential calculus.


You must specifically comprehend the idea of a dimension and what it entails for any arithmetic issues you come into.

The number of directions an item may travel in space is what we refer to when we talk about an object’s dimensions.

  • 2 dimension: Capable of vertical and horizontal movement. It is the unit of “area.” With two coordinates, every place can be described (x,y).
  • 3 dimension: May alter the depth and travel vertically, horizontally, and both. It’s the unit of “volume.” With three coordinates, every place can be described (x,y,z)
  • 4 dimension: may travel through time, both vertically and horizontally, and at different depths. The term “space-time” describes it. With just four coordinates, every place may be described (x,y,z,t).

Most of us will never come across higher dimensions when studying physics.

You’ll need to compute the fundamental forms’ areas and volumes and their sums of internal angles.

Although it may seem simple, you shouldn’t have to waste mental resources calculating angles or the size of the thing you’re dealing with.

The study of matter, energy, and their motions across space and time is known as physics.

As a result, every equation you learn and every issue you resolve will need you to establish a connection between space, time, matter, and energy.

Note: Physics is extremely mathematical in the future. This is one reason it’s crucial to build a solid foundation in mathematics.


Concepts You Should Understand for Elementary Physics

We can resolve every issue you come into by using one of Newton’s Three Laws of Motion until you learn about current physics concepts (quantum mechanics and Einstein’s theories of special and general relativity).

Newton’s Laws of Motion

Newton’s Three Laws of Motion hold true for all systems, particles, electric charges, and magnetic fields, whether dealing with electromagnetism, sound waves, or classical mechanics.

It never really matters how complicated the issue is or how challenging the math is—the key is always figuring out how to:

1. Newton’s First Law and Newton’s Third Law describe how to balance a force on an item in order to account for its position or constant speed.

2. Newton’s First Law and Newton’s Second Law state an item can move if the forces acting on it are out of balance.

Do not forget that a force is anything that moves an item. Physics is the study of natural forces.

Keep in mind that nothing defies Newton’s Three Laws of Motion in the physical world. This will make it easier for you to feel at ease when solving issues.

Energy Conservation

Energy conservation is the second crucial idea you’ll come across most frequently.

The First Law of Thermodynamics refers to this specifically. Energy can only be transported or transformed from one form to another, according to the statement, “energy cannot be generated nor destroyed.”

The starting point determines the ending point.

No conversion is 100% efficient, thus there will always be some heat loss even if this isn’t the most accurate version of the law. It is still helpful for making forecasts and performing computations.

Most students taking Physics 1 and 2 or basic physics are not asked to account for heat loss.

You’ll run into a lot of issues that are related to a system’s overall energy. The sum of a system’s kinetic and potential energy is the system’s overall energy.

The system gains kinetic energy if some potential energy is lost, and vice versa, but the overall amount of energy remains unchanged.

The conservation of mass is a common way to convey this concept while discussing collisions.

Although the arithmetic is slightly different, the fundamental concept is the same: no matter what changes a system undergoes over time—assuming nothing is added to or taken away—the overall amount of energy stays constant.

Learning Elementary Physics

Do you know the distinction between current and voltage or between speed and velocity?

Be Exact in Your Terminology and Familiar With the Meanings of Physics Terms

What about the distinction between volume and force or between area and area? Alternatively, what’s the relationship between displacement and distance or pitch and volume?

In everyday speech, these terms are interchangeable, yet they have a distinct meaning in physics.

These are only samples, but if you don’t understand what they mean, you might find yourself in a lot of trouble.

Despite the fact that physics is a math-intensive field, in order to solve an issue, you must first be able to effectively explain it.

Many of the problems that students run into result from them not understanding what a phrase implies.

In physics, you must be assured that you understand the meaning of each term in the problem. If not, your odds of coming up with the wrong answer rise.

Be Able to Explain Things in Your Own Terms

The famous quote from Albert Einstein goes, “If you can’t express it clearly, you don’t understand it well enough.” This is especially true in the field of physics.

Physics-challenged students frequently treat the topic as if it were something they could simply learn and regurgitate.

As a result, they never stop to think about what’s going on. This student’s attempts to characterize any physics phenomenon always appear as though they are paraphrasing verbatim from a textbook or dictionary.

The words are still fresh in their minds, but they do not understand what they imply.

After instructing physics, I frequently saw this. This is what Richard Feynman called “fragile knowledge.”

When a person can comprehend a concept in a textbook environment but cannot apply it to any situation outside of that setting, they are said to have fragile knowledge.

Students with brittle knowledge cannot apply what they have learned. Many students discover for the first time when studying physics they cannot only rely on memorization and regurgitation.

When I asked the pupils what an object’s acceleration because of gravity is, they could not give me a precise answer for the gravitational constant.

Most students know that the old “G” = 9.81 m/s-1 is equivalent to the acceleration of an object owing to gravity, but most are unaware of this.

Concentrate on making sure you can explain anything clearly to avoid falling victim to this inclination.

I always required this of my pupils, and I wouldn’t take their justification if they were paraphrasing from a book.

Possess the Ability to Translate a Concept Into Its Mathematical Form

All physics phrase has a mathematical definition. This is intentional since numbers are the only method to explain the cosmos uniformly and precisely in physics.

You ought to translate an equation into a word problem and vice versa.

When you can glance at the numbers and quickly know the word (or words) to describe them, you’ll be more adept at solving issues.

Similar to this, whenever you encounter a word, you should immediately consider the equivalent formula or mathematical expression.

Consider the word “momentum,” for instance, and notice how it differs from “force” as well as the equation that leads to it.

Finding the distinction between “velocity” and “acceleration” follows the same logic. The words no longer seem to be as comparable when you look at the word’s math.

Avoid Memorization

If you cannot derive a formula, it is important to not use it. Even if you can bring a formula sheet to the test in most physics schools, this is still good advice given physics.

Simply said, the formulae are there so you won’t have to waste brain resources trying to remember them.

Physics is carried out in math, however, that is not the focus of the issues.

You are not pursuing a career in mathematics. You are practicing physics. You must thus concentrate on mastering that skill.

Yes, you must be proficient in mathematics in order to solve issues and comprehend how things relate to one another.

The formulae and equations are only various instruments to assist you.

To avoid performing the mathematical equivalent of using a pair of pliers to tighten a bolt or a jigsaw to cut a piece of wood, you must grasp the purpose of each instrument.

Making sure we could construct a viable equation from scratch was not the goal of my professor’s suggestion.

It was done so that we could comprehend how to apply the equation, what the consequences of the equation should resemble, and be aware of the constraints placed on each equation we had at our disposal.

If you can do all of that, you will avoid applying the incorrect equation, a complex equation to answer a simple issue, and other mistakes that happen when you try to just “plug and chug” your way to success.

Envision Everything, Then Connect It to Your Experience

Physics always mimics reality, although it causes a significant amount of mathematics—so much so that everybody with a physics degree also receives a minor in mathematics.

This shows that it’s fairly simple to visualize anything you learn about in classical physics.

Until you take the time to draw instances and real-world experiences of these forces, impulse, and circular motion might be difficult to understand.

If you make the instances relevant to you personally, this will be powerful. They frequently cited the operation of an airbag as a real-world illustration of impulse.

That was useful, but when I considered how in boxing you roll with the blows to decrease the force you absorb, I could appreciate the notion much more deeply.

In contrast to other sciences, physics is unique because it quantifies prior experiences.

The mathematical distinctions between acceleration and velocity can be beyond your comprehension.

However, you know you can walk on a bus when it is traveling at a constant pace as opposed to when it is climbing a slope.

Even if you don’t understand the particular method for determining friction coefficient, you know that running on ice is more challenging than on asphalt.

Draw It if You Can’t Picture It

is physics hard

A drawing can depict anything in physics. You can sketch anything you learn about in classical physics since it is a discipline that models and describes how matter and energy interact in space and time.

This is a fantastic tutorial on drawing them if you have never been taught this.

These straightforward illustrations make it easier to understand the forces at work, although some individuals might find them to be overly simplistic.

When I found solutions to many difficulties, I loved creating whole boxes with relative size, springs, and vectors of the proper length.

What you desire doesn’t matter. It just matters that you develop the practice of sketching the issues.

You cannot perform physics in your thoughts. It is an everyday occurrence that you can measure with figures and depict with straightforward illustrations.
